Shakespeare, who also goes by the name "Cecelia Gayle Ferris," was arrested May 28 and had her initial court appearance May 29. Her arraignment and detention hearing were May 31, and documents state Shakespeare pleaded not guilty to the charges against her.

Officials decided to detain Shakespeare "due to (her) history and characteristics, including multiple DUI convictions since 2009." According to documents, "the court finds there are no conditions, or combination of conditions, to ensure the safety of the community." She reportedly is not eligible for bond because "there are detainers from other jurisdictions."

Shakespeare will be the subject of a jury trial Aug. 5 in Cheyenne. If she is found guilty, penalties may include up to 10 years imprisonment, a $250,000 fine, three years of supervised release and a $100 special assessment.

The case is being investigated by the Federal Bureau of Investigation.
